V the same comprises Patented May 17, 1927 This invention relates to drlatora and par- 'ticnlarly' to devices of this character which are provided with heating elements in order to enable the dilatorsto exert a effect byjthe action 'oiheatj v Accordingly, this inventionfaims to provide anrovel dilator construction having an electrical heating element fitted with an 1511 1 proved electric insulating element' a'dapted therapeutic to maintain the heating unit in proper o e element "and thus eliminating any kinks or bends that might r'es'ult from the insertion I invention will now be described by reference I of the heating unit into the dilator body.

It is also sought to; provide a-dilator 1 having an exterior tapered portion inter mediate its ends, for facilitating the a pii: cation of the device 'intoiop'erative position,

said tapered portion being also'formedwith a shoulder tending to oppose any casual displacement of the device while inoperative position.

In the draWinga Figure 1 is a plan view, partly broken away, showing a dilator construction embodying the proposed features of improvement; v

Figure 2 is a longitudinal section taken on the line IIII of Figure 1;

of the *leg portions or the insulating ele ment 15 will springinto'frictional en'gage ment with the' i nteribr 'oi the-casing 8, and

thereby oppose-any withdrawing action of the heating assembly, as will be readily understood. The ends of the heating wire. 14: are received in the usual form of plug 17 a and secured theretoby'clampscrews 18, the I plug 17 having a reduced portijon l'l for fitting in themouth or open, end ofthe eas ing'8, as clearly shown in Figure12. The -i plug 17 has the usual posts 20 for making electrical connection with thefsocketfrnem ber 21 (Figure 1), whereby; the device may besupp-lied with electric energy from any suitable source. In assembling the heating v unit within the casingl8 of the device, it

will be understood that the heating Wire 14 is connected to the plug 17"and secured thereto by the screws 18, and then the assem- 'bly 1415is thrust into the interior ofthe casing 8tot-he full depthofthereduced portion 17' of the plug 17 within the mouth or open end of the-easing that is, till its shoulder portion-19 isistoppedagainst the i outer. face of the flange 10. In this insertingmovement, thelegs 15 of the: insulating the insulating element 15, remainssubstantially stationary, a slight tension is imposed 3 upon the'heating wire ll, thus straightening 'OLltfiIlYEGI'OOkS or'kinks in the wire, and the, supportingaction of the element 15 and the plug 17 serves to maintain the wire 1a in substantially central position within the interiorofthe casing S, with the branches of ,'the.wire-separatedeproperly out: of contact with each other, as clearly illustrated in Figure 2. The plug l7, is now secured in this slightlywithdrawn. position from the =casing 81by' meansofa clamp screw 22 fitted through'the flange 10 andengaging a slight depression .23 in the plug "17.

' It will thus-be apparent that'I have devise'dga practical" and eflicient" device for :carrying out the objects oftheinvention, and thatjthe same is adapted for usein any V open at one end, a plug for the open end of of the applieations in which adevice of this have. illustrated"and describedrwliat I now regard as the preferredform of construction for embodying the improven'ients,pl desire, to reservethe right to makeaall such changes 'or modifications jas may fairly fall within .1 th scope of thelappe'nded claims; ,j

within saidjcasing, a Uwshapedv insulating element carrying said heating element and .haw ing. its free ends located adjacent the a hollow casing open end of'said casing, said insulating eleopen atone end, a'plug for the open end of said casing, a heating element connected to, said plug, and arisilient U-shaped insulat ing element supporting said heatingv element out of contact 'with the interior of. the casing, said insulating element having'its free endslocated adjacent to said plug and adapted for frictional engagement with the interior of the casing. v

3. A dilator comprising a hollowicasing open at one end,'a; plug for the'openl end of said casing, a heating element connected to 7 said plug, and afreslhent U-shapedaln'sulat-l 7 'ing element of slightly less length of said heating element and-adapted-to support the latter outof contact with the interior of the caslng, said insulating element'having its free ends in frictional engagement with the interior of the casingadjacent to said plug,

whereby aslight withdrawal of the'latter will effect a'tensioning of the branches of said heating element, r Y 4. A dilator comprising a hollowncasing said casing a heating element connected to said plug, and a resilient U-shaped 7 insulat- 1'ng element of slightlyless length of=said and means for securingsaid plug in slightly spaced relation to the-ends ofsaid insulating element for, maintaining the branches of interior offthe easing adjacent to said plug, I

said heating element under slight tension. In'iwitness' whereof I hereunto affix my signature. I 1
